Let's build a Trello automation system that:

Automatically progresses cards across board lists
Validates card completeness
Generates AI-powered summaries for code review
Integrates with Slack for notifications
Monitors due dates and sends overdue alerts

Board Structure

The Trello board is organized into four main lists:

New Cards: Entry point for all new cards
In Progress: Active development stage
Needs Review: Code review stage with AI summaries
Completed: Successfully reviewed and approved cards

The Steps

trello-webhook.step.ts

trello-webhook-validation.step.ts

validate-card-requirements.step.ts

start-assigned-card.step.ts

mark-card-for-review.step.ts

complete-approved-card.step.ts

check-overdue-cards.step.ts

slack-notifier.step.ts

Visual Overview

Here's how the automation flow works:

Card Validation → Checks for required information
Progress Tracking → Moves cards between lists
Review Process → Generates AI summaries and notifies reviewers
Completion Handling → Processes approved cards
